Abstract (en)

[origin: WO2020135206A1] The present disclosure relates to systems and methods for intra prediction. The methods may include obtaining a current chroma block; obtaining a plurality of luma prediction modes, wherein the plurality of luma prediction modes includes prediction modes at a plurality of positions of a luma block associated with the current chroma block; and selecting a luma prediction mode from the plurality of luma prediction modes as a candidate chroma prediction mode for predicting samples of the current chroma block.
